Abstract

L’invention concerne un procédé de sélection d’un mode de fonctionnement, parmi au moins deux modes de fonctionnement, d’un dispositif de capture d’images (2) utilisé pour effectuer une reconnaissance faciale d’un occupant (5) d’un véhicule (4) automobile. Selon l’invention, le procédé comprend les étapes suivantes : - la détermination d’une valeur représentative d’un paramètre de positionnement du véhicule dans son environnement ; - la sélection, sur la base de ladite valeur, du mode de fonctionnement. Figure pour l’abrégé : Fig. 1The invention relates to a method for selecting an operating mode, among at least two operating modes, of an image capture device (2) used to perform facial recognition of an occupant (5) of a motor vehicle (4). According to the invention, the method comprises the following steps: - determining a value representative of a positioning parameter of the vehicle in its environment; - the selection, on the basis of said value, of the operating mode.
